Daniel,
I didn't include any code as I didn't do anything unusual but if you think
that would help here it is.I was hoping that there was some ordinary
theoretical basis for this as I didn't do anything custom really, aside
from the id generation for the "Entity" class, which I generate the id
manually much like an Oracle sequence object, I do this in order to
facilitate the creation of relationships between arbitrary objects.
Any help is appreciated
